Below is a position-versus-time graph of an object. Letters A to E represent different segments of its motion. Using clear sentences, describe how this object move in the whole 19 s. In your description you must specify the starting position, the direction and magnitude of velocity for each segment, and the final position when the movement ends.

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
